LAN shared Internet IP settings

The principle is to connect the external network with the machine as a gateway:

1. The IP and DNS of the other machines are set to auto-fetch with the 192.168.0.1 of the network connection.

192.168.0.1 seems to be the default as a gateway, no IP, automatically looking for IP for 192.168.0.1 machines, and requesting IP.

Benefits, LAN internal machines do not care about IP settings and gateway settings,

Disadvantage, the initial state does not have IP, it takes some time to find 192.168.0.1 machine, request IP

2. The machine IP connected to the extranet is set to 192.168.AAA.BBB, and the IP of the other machine is set to 192.168.aaa.xxx,

The gateway and DNS are set to a machine IP that is connected to the extranet,

Benefits, LAN internal IP is fixed, can be fixed IP to access each other's computers

The above conclusions do not have any scientific basis, under WinXP, the phenomenon shows that through
